Bit allocation dependetnt on masking threshold and floor1 inverse dB lookup table
...o set the floor at 50 dB so the
residue values will take less bit to encode. For 50 dB, the linear frequency
value is 316.22 and inversed value is 0.0032487691. So to get the residue
value we need to divide the real frequency value by inversed floor value,
what gives much bigger number. For example 53dB is 446.68 in linear scale
divided by 0.0032487691 gives much bigger value. Why is it done in that way
and how it helps to reduce bits when used with masking thresholds?
The second question is related to the bit allocation of frequency bins
dependent on masking thresholds.
Do you have some good ref...
